Irish Broadband Expands its Alvarion Broadband Wireless Network, Adds Wimax-Ready Systems

Orders for BreezeMAX™ and Breeze ACCESS™VL total over US $1.4 million

Tel-Aviv, Israel and Dublin, Ireland, November 4, 2004 - Alvarion Ltd. (NASDAQ: ALVR), the world's leading provider of wireless broadband solutions, today announced the receipt of follow-on orders valued at $1.4 million from Irish Broadband, for both BreezeACCESS VL and BreezeMAX, Alvarion’s WiMAX-ready platform.

Irish Broadband will be using BreezeACCESS VL to expand an existing Alvarion-based network operating in 5.7GHz, while they will use their recently awarded 3.5 GHz licenses to deploy the BreezeMAX 3500. BreezeMAX will enable Irish Broadband and their subscribers to enjoy the benefits of WiMAX technology that include high service quality with Non-Line-of-Sight (NLOS) functionality plus long-term cost effectiveness.

Irish Broadband is a competitive local exchange carrier (CLEC) that currently serves business and residential customers in Dublin, Cork and Derry in Northern Ireland. The BreezeMAX network will extend coverage to the cities of Dundalk, Drogheda, Galway, Limerick, and Waterford.

Launched in May 2003, Irish Broadband’s wireless broadband network was built originally in the 2.4GHz spectrum using Alvarion’s BreezeACCESS™ II equipment. Leveraging the success of that network, in October 2003, Irish Broadband began expanding into the unlicensed 5.7GHz spectrum using Alvarion’s new OFDM system, BreezeACCESS VL. The 5.7GHz network was rolled out alongside the 2.4GHz network with 5.7GHz base stations also being used to backhaul 2.4GHz base stations for increased range.

Paul Doody, Managing Director of Irish Broadband, commented, “There’s no doubt that WiMAX is the future for operators building broadband wireless access networks. WiMAX will lower the prices of CPEs - savings we will be able to pass onto our customers. BreezeMAX is a natural evolution and standardization of the Alvarion technology, which we have been successfully using for 16 months. Alvarion is most definitely our vendor of choice.”

Zvi Slonimsky, CEO of Alvarion, said, “Irish Broadband is an important customer who understands that installing our BreezeMAX plots a clear roadmap to the future in the WiMAX revolution. As a result, their customers are getting access to affordable broadband connections and the latest networking services. Yet again, the lure of WiMAX is proving to be as strong as we anticipated.”
